Re: Graphics Card For HP Compaq DC7900 Small Form Factor

I tried to install Clib 3d radeon hd7750 on my dc7900 sff. When i start my conputer it runs a while normally but after like 30 seconds Power supplys fan start run with very speed and computer wont boot to windows. So i think that my power supply doesnt provide enough power. Did you had this kind of problems????

Re: Graphics Card For HP Compaq DC7900 Small Form Factor

To answer your question, no, I did not encounter the problem that you have.

For the record my (SFF) dc7900 uses the stock power supply, and that I'm using HIS 7750 iCooler (not that it is any much different from the Club 7750 HD that you're using). I put the settings to maximum clock (using the pre-bundled ATI software). No issues.

Try removing the card, and switch your PC on and see if the problem persists. I'd also clean out your PC (and PSU) of dust, update the BIOS, and ensure that your power source (mains) is supplying a good constant current.

Other than that, I'm not really sure what could be the underlying cause (because I'm not using the Club card, I'm using the HIS card). Hope you get this solved - Regards
